BUNDLING-PRESS.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed October 22, 1907. Serial No. 398,569.

To all whom it may concern:

Be it known that we, TALBOT C. DEXTER and CHARLES O. L. OARDELL, citizens of the United States, and residing at Pearl River,

' in the county of Rockland and State of New York, have invented certain new and useful Improvements in Bundling-Presses, of which the following is a specification.

Our present invention relates to improvements in mechanically operated presses for compactly bundling sheets or signatures into convenient form for storing.

More particularly our invention relates to improvements in automatic tripping mechanism for such bundling presses, whereby the power is thrown out and the action of the press is arrested when the compression has reached a certain predetermined degree in such a manner that the press after being stopped by the tripping mechanism on its operation in one direction can be thrown in by the operator only in the other direction.

Our improvements while shown in this application on a single bundling press, may be also used in the so-called double bundling presses as shown for instance in the Patents No. 819,983 and No. 819,984 to T. C. Dexter without departing from the spirit of our invention.

In order that our invention may be fully understood, we will describe same with reference to the accompanying drawings, and furthermore point out the novelty more particularly in .the annexed claims.

In said drawings: Figure 1 is a plan view of the part of the press comprising our invention omitting an operating hand lever shown in Figs. 3 and 4. Fig. 2 is a front elevation thereof; Fig. 3 is a side elevation of the whole machine on a smaller scale seen from the right hand. side of Fig. 1; Fig. 4 is a side elevation of the tripping mechanism seen from the left hand side of Fig. 1; Fig. 5 is a rear view of the fork for shifting the clutch collar; and Fig. 6 is a detail longitudinal sectional view of the clutching device preferably used in our machine.

While the frame work of our improved bundling press may be of any suitable form and construction to properly support the operative parts of the mechanism, we prefer the form shown in Fig. 3, in which the two uprights, 10 and 11, are suitably shaped to support the bundling trough obliquely, by

which arrangement certain advantages in feeding the machine are obtained.

The frame pieces or uprights 10 and 11 are suitably braced together by the web 12. On the right hand side of upright 10 (Fig. 3) is mounted frame 13 which carries the trough in a similar manner as shown in the patents above referred to. The head piece 14 of up right 10 is suitably shaped to correspond with the form of the compression heads 15 and 16 to be described later on, and furthermore adapted to serve as a bearing for the upper end of the compression screw 17. The lower end of screw 17 is journaled at 18 in the upper end of upright 11 in the same manner as described in the patents above referred to. The stationary compression head 15 which is of similar shape as that shown in the patents above referred to rests upon frame 13 on which it can slide a short distance toward the head piece 14 of upright 10 of corresponding shape and from which it is held at a suitable distance by springs 19 of sufli cient strength to withstand the degree of compression which it is desired to apply to the bundles placed under compression. The corresponding and movable compression head 16 is also slidingly disposed on frame 13 and rigidly connected by rods 20 rovided on either side, with cross bar 21 disposed between uprights 10 and 11 and operated be-' tween these two' uprights by compression screw 17 which passes through its middle. The power shaft 22 through which the machine is operated is journaled between the two ends of U-shaped frame 23 which forms part of the upper portion of upright 11.

24 is a bevel gear keyed to the power end of screw 17. This gear 24 is in constant mesh with similar bevel gears 25 and 26 which are loosely journaled upon the power shaft 22, each gear 25 and 26 being arranged adjacent to one of the shaft bearings 27 and 28, respectively (Figs. 1 and 2).

Combined with each of the loosely mounted gears 25 or 26 is a friction band clutch of ordinary construction, the rim portion 29 or 30 of each clutch being formed integral with or rigidly attached to one of the gear wheels, while the expansible band portion of each clutch is keyed to the power shaft and carries the usual pivoted lock arm 3 1 which is adapted one of the gear wheels (26) with its clutch is shown in Fig. 6. This clutch spool 32 is suitably mounted upon power shaft 22 and is capable of sliding longitudinally upon said shaft in either direction to actuate either clutch, so as to lock either of the bevel gears 25 or 26 upon the power shaft; Clutch spool 32 is formed with an annular groove 33 (Fig. 2) in which engages the forked lower end of actuating arm 40. The upper end of this arm, which is formed into a sleeve 41, is securely fixed to rod 42 disposed above gear wheels 25 and 26 and sliding in bearings 43, 44, mounted on the shaft bearings 27 and 28, respectively. Between sleeve 41 and slide bearings 43 and 44 are disposed on shaft 42 springs 45 and 46 tending to hold sleeve 41 in the middle or neutral position between bearings 43 and 44, as shown in Fig. 2.

Between head piece 14 of upright 10 and bearing 18 of upright 11, extends a frame portion 47 T-shaped in transverse section which is suitably fastened at both ends to its respective supports 14 and 18 and provided on the upper side with studs 48 and 49 as shown in Fig. 3. On stud 48 is pivoted hand lever 50 omitted in Fig. 1, by means of which the machine is thrown in and out of operation. The other arm 51 of the hand lever 50 is loosely pivoted in pin 52 ofboss 53, forming a part of sleeve 41, so that when hand lever 50 is operated transverse to the longitudinal axis of the machine, sleeve 41 and thus forked arm 40 will also slide transversely to the machine and cause clutch spool 32 to connect power shaft 22 with either gear wheel 25 or 26. It will be seen that thus screw 17 may be operated in either direction and thus compression head 16 be caused to move toward or away from stationary compression head 15 in a similar manner as shown and described in the Patent No 819,983 above referred to.

On stud 49 of frame bar 47 is fixed arm 54 extending from stud 49 in the direction to wards rod 42. The end of this arm is suitably shaped to form a bearing for rocking shaft 55, which protrudes on either side of arm 54 as shown in dotted lines in Fig. 1. To the left hand end of rocking shaft 55 is loosely fitted three-armed bell-crank 56, the form of which is shown in Figs. 1 and 4. This bell crank is adapted to perform a slight oscillating motion whlchis limited by a pin 57, fastened in rocking shaft 55, and projecting within a slot 58 in bell crank 56. On the right hand end of rocking shaft 55 is loosely fitted bell crank 59, the rocking motion of which is limited in a similar manner as described with reference to bell crank 56, by having pin 60 fixed in rocking shaft 55 and passing through slot 61 provided in bell crank 59. On this right hand end of rocking shaft 55 is further fastened hand lever 62 extending upwards by which rocking shaft 55 may be rocked by hand if desired. Arms 63 and 64 of bell cranks 56 and 59, respectively, extend forward parallel to and underneath arm 51 and are shaped as shown in Fig. 1 and are provided at their ends each with a locking plate, arm 63 having the locking plate 65 fastened to its upper side (Figs. 1 and 4) and arm 64 having its locking plate 66 fastened to its under side. To the rear side of sleeve 41 is suitably fastened the shoulder plate 67 shown in full view in Fig. 5, representing a rear view of shifting rod 42, sleeve 41 being in this figure covered by shoulder plate 67. The respective locking plates 65 and 66 bear against the upper and lower edges of the shoulder plate 67, as shown in Fig. 4. In the detail rear view, Fig. 5, the locking plates 65 and 66 are cut off, but their positions relatively to the shoulder plate are indicated in dotted lines and by reference numbers. In the latter figure it will be seen that plate 67 is provided with a shoulder 68 at the right hand side of the upper edge and with shoulder 69 at the left hand end of-the lower edge, shoulder 68 being disposed near locking plate 65, and shoulder 69 near locking plate 66. Locking plate 65 is held in engagement with the upper edge of plate 67 by means of a spiral spring 70 (Fig. 4) abutting against a collar 71 of rod 72 pivoted to the left hand arm of hell crank 56 and abutting with its lower end against frame 23, so that locking plate 65 of arm 63 of bell crank 56 will be held yieldingly against the upper edge of plate 67 The lower locking late 66 fastened to hell crank arm 64 of be l crank 59 is held yieldingly in engagement with the lower edge of plate 67 by means of spiral spring 73 disposed on rod 74. This rod is pivoted on one end to the downward pointing arm of bell crank 59 (Fig. 3) and guided at the other end in stud 75 disposed on frame bar 47, spring 73 abutting at one end against this stud and at the other end against collar 76 fastened to rod 74.

It will now be seen that if the shifting rod 42 carrying the plate 67 be shifted to the right in Fig. 1' (i. e. to the left in Fig. 5) so as to lock the gear wheel 25 to the power shaft 22, which is driven in the direction indicated by the arrows, the locking plate 65 will slip behind the shoulder 68 of plate 67 so as to prevent the shifting rod being returned to its normal or central position by means of the compression spring 45. With the parts in this position the bevel gear24 and compression screw 17 will be rotated to the left, so as to draw the moving head 16 toward the stationary head 15 in order to compress the bundle. If on the other hand the rod 42 carrying the shoulder plate 67 be shifted to the left in fig. 1 (i. e. to the right in Fig. 5) so as to lock the bevel gear 26 to the power shaft and reverse the compression screw, the locking plate 66 will slip behind the shoulder 69 and will prevent the shifting rod 42 from being returned to normal central position by the force of the compression spring 46.

Before starting the press forward by locking the bevel gear 25 to the power shaft as first described, the sheets or signatures have been inserted between compression heads 1.5 and 16. When the desired compression has been reached springs 19 holding stationary head 15 at a suitable distance from head piece 14 will yield and cause compression head 15 to move towards head piece 14 in which movement it will strike pin 81 disposed within and protruding through head piece 14. To the other end of pin 81 is suitably fixed rod 82 pivoted at its other end to the downward pointing arm 83 of bell crank 56 (Figs. 1 and 4). It will now be seen that if compression head 15 continues to move toward head piece 14, it will take along pin 81 which in turn will cause bell crank 56 to rock and lift locking plate 65 from its shoulder 68, so that plate 67 with the sleeve 41 is free to be returned by compression spring 45 into its middle or normal position, thereby unlocking bevel gear 25 from power shaft 22 and stop ping the operation of the press. On the other hand if, after tying the compressed bundles together in the manner described in the patents above referred to, the press is to be operated the reverse way in order to release the tied bundles from between compression heads 15 and 16, sleeve 41 is shifted to the left (Fig. 1) which will cause locking plate 66 of bell crank 59 to slip behind shoulder 69 as described above, thus preventing gear wheel 26, which has been locked to power shaft 22 by this shifting operation, from becoming unlocked from this shaft. Compression screw 17 will now revolve the reverse way and move compression head 16 away from stationary compression head 15.

In order to cause head 16 to stop on its rear ward movement before it reaches the rear end of frame 13, the following throw-out has been provided. To the downward pointing arm of bell crank 59 (Fig. 3) is pivoted rod 84, the other end of which is slidingly disposed within boss 85 provided on cross arm 21. Furthermore a collar86 is fiXed at a suitable place on rod 84 against which boss 85 will abut on the rearward motion of arm 21. In taking along thus rod 84 on this rearward motion bell crank 59 will be rocked, thereby lifting locking plate 66 from its shoulder 69, which will cause sleeve 41 now being free to be returned to its normal position by means of spiral spring 46. This will unlock gear Wheel 26 from power shaft 22 and stop the rearward motion of head 16.

In case it is desired to stop the operation direction, thus operating either bell crank 56 or 59 and thus operating the throw-out device of either side.

Thus far the automatic tripping or throwout device for the press is substantially the same as shown in the Patent No. 819,983, above referred to. The tripping mechanism, however, as described above will not prevent the operator from throwing the machine into operation for running in the same direction in which it has been previously tripped, which would cause, owing to undue stress on the different parts of the machine a destruction of same, or at least a jamming of the compression screw in the cross bar. In order to prevent the operator from starting the machine in the same direction in which it has been tripped, we have provided the following safety device. On boss 53 (Fig.4) are provided the studs 87 and 89 to which is fixed upward extending bracket 90. At the lower end of bracket is pivoted at 93 double dog consisting of horizontal arms or fingers 97, 98 and a vertical arm 92 pivoted at 91 to a rod 88 guided in the upper portion of bracket and with which rod this arm 92 forms a toggle joint. Underneath double dog 92 is disposed bar 94 suitably fastened at its ends to brackets 43 and 44 (Figs. 1 and 2). On the upper side of bar 94 are provided the tripping fingers 95 and 96 and furthermore the notches 99 and of suitable shape to engage the fingers 97 and 98 of double dog 92. Assuming nowthat double dog 92 be in the position shown in Fig. 2 and sleeve 41 is shifted to the left in order to lock gear wheel 26 to power shaft 22 to free the bundles from between compression heads 15 and 16 as described above, then it will be seen that finger 97 of double dog 92 will slip under tripping finger 95, which is suitably shaped to cause finger 97 to move toward bar 94. This will operate the toggle joint, which in turn will throw finger 97 down onbar 94. If now the operation of the press is stopped by the tripping mechanism in the manner above described and sleeve 41 has been thrown back to its normal position shown in Fig. 2 by means of spring 46, finger 97 will slip into notch 99 and prevent sleeve 41 from being thrown again to the left, thus preventing the press from being started again in the same direction. The shifting rod 42 and sleeve 41, however, are free to be shifted to the right hand side (Fig. 2), which will cause the press to operate in the other direction until stopped by the tripping mechanism for this direction, also above described. In throwing shifting rod 42 to the right toggle joint 91 has been thrown by means of tripping finger 96 into the position shown in Fig. 2. On returning of sleeve 41 into its normal or middle position after the tripping device for this direction has operated, finger 98 of double dog 92 will slip into notch 100 of bar 94 in which it is shown in Fig. 2, and prevent sleeve 41 from being shifted again to the right, thus preventing the press from being started again in this direction.
